On AMC’s hit series, Mad Men, January Jones plays Betty Francis, but when we were first introduced to the character, her name was Mrs. Don Draper. Ever since her split from the slick ad man, Betty slowly morphed from a wholesome housewife into a vindictive ex who loathes seeing her former husband, and his new wife, happy. She’s even gone so far as to divulge details about Don’s secret past to the former couple’s young daughter, Sally.
